Diabetes as a Negative Factor on the Hair Growth Cycle



Diabetes is a problem affecting many areas of your life starting with the level of insulin. Why is the proper working of insulin hormones is significant for your life? It is because as a hormone moving the sugar from each food you eat from your bloodstream into your cells so that it can be stored or used as energy if it is needed.

However, not working properly of insulin might mean the fact that sugar you take from the food can build up in your blood.

That means there will be some excess supply of sugar in your body, which might damage your organs all over your body. It has affection surely all your body such as your eyes, nerves, and kidneys.



Even your blood vessels are affected by this change. since the blood vessels are responsible to carry oxygen around your body so that it can nourish your organs and tissues.

When you have diabetes, it means the working would be problematic in terms of delivering enough oxygen to feed your hair follicles and there will be some missing part of oxygen level.

Needless to say, the lack of oxygen has a negative influence on the optimum level of the hair growth cycle.



What Is the Hair Growth Cycle? There are three main stages of hair growth period: Anagen Phase, Catagen Phase, and Telogen Phase.

While the Anagen phase, the first stage, is also called the growth phase, as where your hair has started to grow properly, the catagen stage is known as the transition phase. This second stage lasts almost three weeks, which is related to less than 1 percent of the hairs on your scalp at a time.

When it comes to the last phase, telogen phase is where the hair prepares itself to be shed. Around 50 and 150 telogen hairs can be and then replaced by new growth daily.

The circle keeps doing after the third one starting from the beginning of everything is okay in the body and hormonal system. Although the pace and the duration of hair growth are determined by the individual’s own genetic conditions generally speaking it is 90 percent of the hair on your scalp growths in this stage averagely.
